ed nen7 and usetul'lmprovements in Wateru Gages, of 'which the following is a specilication.

`lnthe usual construction. of water gages for boilers, ythe glass is held between ltwo plates, which constitutel the body of the gage, the saidplates being, connected by of the platesand liavetheir threads coengag ing )with threaded openings inA the other plate: The Water constantly in the gage not infrequently"causes the corrosion of the bolts, such disintegration materially Wealo ening the ysaid bolts as Well as causing an adhesion between the'l threads in the bolts and the threads in the depressions or openings engaged by the bolts. The result is, `when the glass breaks or when there are othervi'easons for separating the plates, the bolts 'do not turn freely in unscreiving and an excessive.pressureupon'the heads of the bolts vtwists( and breaks the weakened stems thereof.' Asa consequence, the removal of the plates orsections of the gage is a matter ofk considerable. diilficulty, requiring a .great ain'ountjoftimeand laborand when the bolts break, as isimost frequently the case, it is necessary to rill the same out of the openin'g'which thefoccupy and to retap the plate. Still agaimthis class of gages requires the employment of bolts of a de termined length and .wherein the threads thereof must necessarily correspond to the pitch of the threads in the depressions or openings receiving' the same.

It may, therefore, be considered the pri- Y mary object of the present invention to prof duce a Water gage wherein the plates or sections thereof .are formed with alining openings, bolts, of any length, being passed through said openings, and nuts, ot any desired size or shape engaging with said bolts to lhold the sections removably and to per` init of the ready separation of the said sections, means being provided upon one of the plates .engaging` with the said nuts for holding` the nuts against 'turning'. so that the bolts may be readily screwed to engage with the nuts -or readili1 unscrewed as desired,

but Vnormali;v held against turning.

y It 1s a still further object of the invention to produce a Water gage for boilers 1n which VA'llER-GAGE.

Other objects' and. advantages will. appear as the nature of the invention'islmore fully understood, reference being had. to the accompanying drawings, in which, Figure l is a 'face View oi' a Water gage for boilers `construct@d in accordance with the present invention.

Fig'. 4 is a transverse sectional view approxiinatelyon the line. 4 4- of Fig. 3.

Fig. 5 is a sectional view approximately on the line 5``of Fig. 3.

Fig. 6 is a 'perspective view of the rear member or plate of the gage, looking to- Ward'the rear face thereof.

Fig. 7 is a transverse sectional. view through theiribs in the rear plate or body, illustrating the said ribs as sepa-rate ein ments from. the body.

Fig. 8 is a section et a slight modification.

Like characters throughout the several views designate like parts.

The gage comprises a rear plate or section l0 and a front plate or' section ll. IThe rear 'plate l0, in reality, comprises the body o?? the gage, the same being cent-rally formed, upon its rear face, with an enlargement 12 which is semi-cylindrical in cross section andA which has its top and bottom closed, except for the connection therewith of the boiler pipes 13 and la the vsaine being provided with the. usual taires. (not shown). The tubular enlargement l2 is preferably reinforced by bot-h longitudinal and transverse rio between the ribs 15 providing pockets vfor nuts 17.

The .outer plate r front member 11 is provided-upon its' iiinerface with a longitudinal depression Corresponding with a similar depression in the outerrfaee of the. rear plate or body 10, the-last -referred to vdepression communicating With. the tubular member '12 ofthe said member 10, vvhile the depression in the'outer .plate 11 is centrally formed with 'an eloliliga-te'd'openngi Vithin each or' these depressions fare" arranged. theusual coinpie's'sible gaskets, and also withinthese depressions and contac'ti'ng with the said gasket is the sightglass -1S'. yThe 'r'o'nt pla-te 1 1 has itssideslanged andthe said liang'e's lap the-sides of the rear plate 10` aiidthe 'said front plate 11 -is proi'jidedivithf aplurality of openings alinngl ivith the bolt openings 16 in therearineinber. 1The'nu-y nierals`19 designate the `bolts thel same bei ing'of any desired size andliaving-hea'ds, ot any desired shape, the shanlisyof the said lbolts being, ihosveveiylofaisize to be freely passedthrough the alinii'ig openings in the plates 'coinl'aris'ing 'the body of` the '.gag and thi-ea 'in-the bore's of thenu't's 1'4'.
